Changes since 1.13: +27 -1 lines

Pull up following revision(s) (requested by pavel in ticket #845):
	etc/rc.d/postfix: revision 1.14
	etc/defaults/rc.conf: revision 1.90
Add some magic (similar to the one in rc.d/sendmail introduced with 2.0
release) to not start postfix if $postfix is not explicitely set and
another mailer is selected in /etc/mailer.conf. Also print a warning if it
happens because the mailer in rc.conf is the removed sendmail.
This prevents starting two MTAs at once if one uses a custom MTA.
As proposed on tech-userlevel, approved by martin.
